Ultra-precision single-point diamond turning (SPDT) is a recent realm in advanced manufacturing of optical components with nanometric features. SPDT has various applications in different industry sectors including space science, biomedical engineering, military, defense, and optics. However, different factors negatively impact the outcome of SPDT process and limit the success of optical surface generation. In addition, standard SPDT is based on the pure mechanical action of cutting and is limited when it comes to turning brittle and hard-to-machine materials. These materials have low machinability, and cutting them with diamond tool has been affected by high tool wear, short tool life, and consequently low quality of optical surface finish. Non-conventional machining techniques have been implemented to assist the purely mechanical SPDT process in order to eliminate the existing limitations, reduce effects of influencing factors, and enable an optimized machining environment. Different methods have been developed and used for assisting the SPDT process. In this review paper, recent trends and advances in technologies used for assisting SPDT are surveyed. Studying constructive and destructive effects of these SPDT-assisted technologies could provide necessary information for using the best possible solutions in diamond turning of different materials while improving targeted parameters. In addition, studying the effects of assisting technologies could provide a good perspective on hybrid SPDT process limitations and possible solutions. Although various techniques and solutions have been developed, there are still limitations for enabling an ultimate turning process. The paper highlights the possible trend of new technologies related to SPDT. More attention needs to be given, especially, to the development of novel techniques to completely solve existing limitations and enable best SPDT performance. Future studies need to be focused on the development of hybrid SPDT platforms, based on suitable combinations of non-conventional technologies, to achieve the best possible quality in terms of optical surface generation.

回顾非常规技术以协助超精密单点金刚石车削

超精密单点金刚石车削(SPDT)是先进制造具有纳米特征的光学组件的新领域。SPDT在不同的行业领域具有各种应用,包括空间科学,生物医学工程,军事,国防和光学。但是,不同的因素会对SPDT工艺的结果产生负面影响,并限制了光学表面生成的成功。此外,标准SPDT基于切削的纯机械作用,在车削脆性和难于加工的材料时受到限制。这些材料的可加工性低,并且用金刚石工具切割它们受到高工具磨损,短工具寿命以及因此光学表面光洁度低的影响。为了消除现有限制,减少影响因素的影响并实现最佳加工环境,已采用非常规加工技术来协助纯机械SPDT工艺。已经开发出不同的方法并将其用于辅助SPDT过程。在这篇综述文件中,调查了用于协助SPDT的技术的最新趋势和进展。研究这些SPDT辅助技术的建设性和破坏性效果,可以为在改进不同材料的金刚石车削时使用最佳解决方案,同时改善目标参数提供必要的信息。此外,研究辅助技术的效果可以为混合SPDT工艺的局限性和可能的​​解决方案提供一个很好的视角。尽管已经开发了各种技术和解决方案,但是在实现最终车削过程方面仍然存在局限性。本文重点介绍了与SPDT相关的新技术的可能趋势。特别是,需要更多地关注新颖技术的开发,以完全解决现有限制并实现最佳SPDT性能。未来的研究需要集中在基于非常规技术的适当组合的混合SPDT平台的开发上,以在光学表面生成方面实现最佳质量。开发新技术以完全解决现有限制并实现最佳SPDT性能。未来的研究需要集中在基于非常规技术的适当组合的混合SPDT平台的开发上,以在光学表面生成方面实现最佳质量。开发新技术以完全解决现有限制并实现最佳SPDT性能。未来的研究需要集中在基于非常规技术的适当组合的混合SPDT平台的开发上,以在光学表面生成方面实现最佳质量。
